Just Dose It Central Heating Dosing Tool, Radiator Dosing Funnel - For Adding Chemicals Like Fernox Central Heating Inhibitor, Sludge Remover, Leak Sealer & Sentinel X100

Boutht it to add inhibitor to my heating system. Makes what could be a messy job easy to complete.

Spillage prevention and ease of access to radiator and fits properly

Easy to use

First off, great looking product. Feels like it would last. Well packaged and threads were nice and shiny. Remember with this product to turn off your water feed and let some water somewhere drain out. This is a £10 product in my view. For someone who knows how to use this product, 35 seconds may be reasonable but for normal / non-plumber inclined people I would put this at 5 minutes. Pouring liquid in to the funnel with its size will take a few seconds.

A must have for topping up central heating system

Arrived on time. Very easy to use. Much easier than (partialy) draining by shutting off the header tank supply and running hoses from the boiler.

Awesome makes life much easier

I recently used the Just Dose It Central Heating Dosing Tool for adding chemicals to my radiators, and while it does the job, there are a few things I think could be better. The funnel is easy to use, and it made adding the Fernox Inhibitor to my central heating system straightforward without any mess, which was a relief. The size of the funnel was also a good fit for my radiator valves, and I appreciated how simple it was to attach it and pour in the chemicals.However, the tool isn’t as durable as I expected. The plastic feels a bit flimsy, and I was concerned it might crack over time, especially with repeated use. It works well for the job, but I would have liked it to feel a bit sturdier.One thing I did like was the clear markings on the funnel, which made measuring out the correct amount of chemical easy. It definitely helped with accuracy, which is important when you’re dosing a heating system.Overall, it’s a decent tool for the price, but I think it could be more robust. It’s handy for adding chemicals without the mess, but I’d be cautious about how long it’ll last. 3/5 for me.
